摘要
Refractive indices and densities for binary dimethyl sulfoxide+water, dimethyl sulfoxide+1,4-dioxane systems and ternary dimethyl sulfoxide+water+1,4-dioxane system have been measured at 298.15 K, over the entire mole fraction scale of the mixture. Changes on molar volume, partial molar volume and molar refraction have been calculated. The experimental data were used to test several mixing rules for estimation of the refractive index.
